The affixoid is a linguistic unit in modern Chinese that lies in the middle ground between roots and affixes, and research on the ontology of class affixes, a class of class affixes and a specific class of affixes has already yielded some results. In this paper, we have selected "霸", which has received relatively little attention from previous researchers. In the course of the paper, the main methods used are documentary research, combination of description and interpretation, and corpus analysis. The paper begins with a definition of the affixoid "霸" in the light of previous research on the definition of affixes, explaining the basic features of the affixoid "霸" and classifying its derivatives. This is followed by a specific analysis of the class affixoid "霸" and its derivatives in terms of syntax, semantics and pragmatics. The grammaticalization process of the affixoid "霸" is then analyzed in order to show how people's mental states and situations change.
